1. Vacuum System: By vacuum tank, vacuum pumps, condensate tanks, fluid tanks, air-filling system.Optimized structure design, greatly increasing the surface area of the oil in the vacuum system, and maximizing oil travel in a vacuum system. The oil in the water and gas are fully overflowed. This machine adopts advanced defaming system so oil filter at work will not appear similar products widespread phenomenon of injection.

2.Filtration system: Using three filter, coarse filter inlet to protect the pump and extend the life of the main filter. After the pump has two fine filter, so the oil quickly reach high cleanliness. Using special gradient filter pore glass fiber material that can be layered filter particles of different size, which greatly improved the life of the filter. The filter has a perfect structure, which can effectively reduce the surface velocity filter, access to stable filtration accuracy.

3. Heating system: Segmented gradual heating surface heat load is small 1.0W / cm2, the oil does not overheat causing deterioration. Oil temperature can be adjusted at 0 ~ 100 ℃, automatic control, and a protective device, the amount of oil is too low today automatically stop working, to avoid damage caused by dry heater.

4. Automatic control system: The machine uses the frequency, level transmitters, temperature sensors, vacuum degree sensing instrument, such as a series of automatic control instruments of various information acquisition device run by the central processor for processing, automatic control of the whole equipment run and monitor the operational status of equipment. The unit comes with a variety of protective devices (overload, overvoltage protection, phase sequence protection, abnormal operation shutdown protection) to ensure safe operation of equipment.

5. The whole structure: Machine integration bridge structure, reducing the volume. Holistic removable tank, ensure that the ground without oil operations, reduce environmental pollution. There are mobile, fixed, fully enclosed, vehicle type, and so many models to choose from.
